CONDENSER.

` Application mea March 15, 192s. serial No. 625,200.

To allan/tom t 71mg/ concern:

` Be it known that I, JOSEPH A. KLAUsn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Condensers, of which the following is a specification.

My invention relates to condensers which are particularly adapted for use in radio transiiiitting and receiving apparatus.

I-leretofore it has always been the practice to combine condensers in such relation to each other as to avoid so far as possible mutual capacities between the parts combined. Nevertheless, there has always been some unavoided mutual capacity between the condenser parts and this mutual capacity has been a detriment to radio practice. In making condensers it is practically impossible to make a condenser of a desired capacity, there being variations from the rated capacity either plus or minus. This condition of condensers does not produce maximum efficiency in radio apparatus.

The object of my invention is to provide a condenser bank which will utilize the mutual capacities to equalize the varying ca pacities of condensers and thereby avoid the above objections and increase the efiiciency of radio apparatus to a maximum.

This object, and other advantageous ends which will' be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a diagrammatic view of a radio receiving apparatus illustrating my invention applied thereto,

Figure 2 a plan view of a condenser constructed in accordance with my invention,

Figure 3' a section on line 8-3 of Figure Q, and

Figure 4 an inverted plan view of Figure 2 showing the interior of the condenser.

My condenser may be used for numerous purposes in radio receiving` or transmitting apparatus and for purposes of illustration, I have shown it as applied to a super-regen erative receiving` apparatus.

Referring to the drawings, 1 indicates a casing which may be made of any suitableV dielectric material. The casing may be of any shape preferably-circular and is provided with a hollow part 2. Condensers 3, 4 and 5 are disposed in the hollow part in a triangular overlapping relation as shown in Figures 3 and 4. Terminals 6, 7 and 8 conneet the overlapping ends of the condensers.

inding posts 9, 10 and 11 are connected to the terminals on the outside of the casing. The binding posts may be of any suitable type. Spring clips 12 and 13 are secured to binding posts 10 and 11 so that they may be Conductively connected by a high resistance conducting means such as the well known grid-leak 14 to permit a small amount of current to4 pass. The hollow part 2 may be iilled with any suitable insulating' plastic material which may be easily hardened to serve as a protection to the overlapping condensers. The super-regenerative receiving` apparatus illustrated in Figure 1 comprises anv aerial circuit 15 connected to the grid circuit 16. A plate circuit 17 has the regenerative tickler-coil 18. The super-regen erative connection is indicated at 19. My improved condenser bank is applied at 20.* The terminal 8 is hooked up to the superregenerative connection 19. The terminal 7 is hooked to one end of the grid circuit 16 and the terminal 6 is hooked to the positive side of the filament circuit.

Viith my condenser bank applied as shown in Figure1, I have found that the efficiency of such a receiving apparatus is increased about utilization of mutual capacities, ordinarily existing between combined condensers, to equalize the varying capacities of the condensers by arranging them in an overlapping relation. In other words the ordinary condensers always vary above or below their rated capacity. By arranging the condensers so that the ends will overlap each other as shown in Figure 4 there is a mutual capacity produced which equalizes the varying capacities of the rated condensers.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit my self to the precise construction set fort-h, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let* ters Patent is 1. A condenser bank including a plurality of condensers which are arranged at an an- This increasel is due to the y gle to each other, and each having its ends overlapped by the adjacent condense-rs and being' arranged to utilize the mutual capacitiesV for equalizing the varying capacities.

2. A condenser bank including condensers arranged at an angle to each other and each having its ends overlapping by the adjacent condensers, and terminal members for fastening together and conductively connecting each set of overlapping ends.

3. A condenser bank including three condensers, triangularly arranged and having their ends overlapping, and a plurality of terminal posts each tor conductively connecting a set of overlapping ends.

(l. A condenser bank including a casing7 binding posts on the casing, angularly arranged condensers with overlapping ends on one side of said casing, and terminals connecting each set o1 overlapping ends and .extending through said casing to .cooperate With the binding post on the other side.

5. A condenser bank including a casing;

terminals in the casing; overlapping condensers connecting one terminal to the other on one side of the casing, and a binding post connected to each terminal on the other side of the casing.

6. A condenser bank including a casing; terminals in the casing; overlapping condensers connecting one terminal to the other on one side of the casing; a binding post connected to each terminal on the other side of the casing, and means for conductively connecting a. pair of binding posts.

7. A condenser bank including a casing; terminals in the casing; overlappingv condensers connecting one terminal to the other on one side of the casing; a binding post connected t0 each terminal on the other side of the casing; spring clips on the binding posts, and means for conductively connecting a pair of spring clips.

In testimony whereof I have signed my name to this speciiication.

JOSEPH A. KLAUSE.
